 What is the difference between physical and chemical weathering?

Physical weathering breaks rocks into smaller pieces without changing their composition, while chemical weathering changes the rock's composition.

100

What is a meander?

A broad, C-shaped curve in a river.

100

What force causes mass wasting?

Gravity.

100

What are glaciers made of?

Large masses of ice that form on land.


100

What is erosion?

The movement of sediment from one location to another.

200

What type of weathering involves tree roots breaking apart rocks?

Physical weathering (root wedging).

200

What landform is created by a river depositing sediment at its mouth?

 A delta.


200

Name a type of slow-moving mass wasting.

Creep.

200

What type of glacier forms in mountains?

Alpine glaciers.

200

What is deposition?

The laying down of sediment in a new location.

300

How does oxidation affect rocks?

Oxidation combines oxygen with minerals like iron, causing rust and weakening the rock.

300

What is the main cause of coastal erosion?

Waves crashing onto the shore.


300

What is a landslide?

The rapid downhill movement of soil, rocks, and boulders.

300

What is a U-shaped valley, and how is it formed?

A valley carved by a glacier moving through it.

300

What are constructive processes?

Processes that build up landforms, like deposition.

400

What is the main agent that causes ice wedging?

Water freezing and expanding in cracks.

400

How do sand dunes form?

Wind carries and deposits sand when it slows down.

400

What human activity can increase the risk of mass wasting?

Removing vegetation from slopes.

400

What is a moraine?

A mound or ridge of unsorted sediment deposited by a glacier.

400

How do glaciers contribute to both erosion and deposition?

They erode land as they move and deposit sediment when they melt.

500

Why does chemical weathering happen faster in warm, wet climates?

Heat speeds up chemical reactions, and water is necessary for many chemical processes.

500

What type of erosion creates caves in limestone regions?

Groundwater erosion caused by acidic water dissolving limestone.

500

What is talus?

 A pile of angular rocks and sediment from a rockfall.


500

What is an outwash plain?

A flat area of well-sorted sediment deposited by meltwater from a glacier.


500

What natural forces drive weathering, erosion, and deposition?

Gravity, water, wind, and ice.
